------------------------------------------------------ From: Lukas Bulwahn lukas.bulwahn@gmail.com Subject: elfcore: correct reference to CONFIG_UML

Commit 6e7b64b9dd6d ("elfcore: fix building with clang") introduces special handling for two architectures, ia64 and User Mode Linux. However, the wrong name, i.e., CONFIG_UM, for the intended Kconfig symbol for User-Mode Linux was used.

Although the directory for User Mode Linux is ./arch/um; the Kconfig symbol for this architecture is called CONFIG_UML.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

UM Referencing files: include/linux/elfcore.h Similar symbols: UML, NUMA

Correct the name of the config to the intended one.
